Homelab Raspberry Pi Kubernetes Cluster

A platform to deploy my self-hosted services onto with almost $0 recurring costs.

Previously, I was running a few things on a Raspberry Pi 3B+. Mainly, Blocky as an ad-blocking local dns cache and some adventures with Home Assistant. A Kubernetes cluster will enable me to easily set up new things and have proper monitoring as well.

Hardware Acquisition

I have 3 spare ethernet ports on my router so I will be using that directly for now. In the future, I may get a switch for them to connect to.

Setup

I'm planning to install Raspian Lite and use k3sup to install k3s. I looked into using k3os directly, but it seems it's still not the easiest for a Raspberry Pi issue.

I will try to manage the cluster in a GitOps style. As such, I will disable installing the Traefik Ingress Controller and Service Load Balancer by default and instead install them separately (or choose a different option).

Networking

I will start out with the default flannel with vxlan, but am considering the wireguard backend. I would like to be able to access some services in the cluster using something like Tailscale as well.
